摘要: Constructing the stable, low-cost, efficient, and highly adaptable visible light-driven photocatalyst to implement the synergistic effect of photocatalysis and adsorption has been excavated a promising strategy to deal with antibiotic pollution in water bodies. Herein, a novel 3D ternary Z-scheme heterojunction photocatalyst Ni2P/Bi2MoO6/g-C3N4 (Ni2P/BMO/CN) was fabricated by a simple solvothermal method in which the broad spectrum antibiotics (mainly tetracyclines and supplemented by quinolones) were used as target pollution sources to evaluate its adsorption and photocatalytic performance. Notably, the Z-scheme composite significantly exhibit the enhancement for degradation efficiency of tetracycline and other antibiotic by using Ni2P nanoparticles as electron conductor. Active species capture experiment and electron spin resonance (ESR) technology reveal the mechanism of Z-scheme Ni2P/BMO/CN photocatalytic reaction in detail. In addition, based on the identification of intermediates by liquid chromatography–mass spectroscopy (LC–MS), the possible photocatalytic degradation pathways of TC were proposed.
